AB  - The HVDC and wind turbine interfaces were attain the researchers interest by its megawatt ratings over the dc-dc convertors ration with high setup. In this stusy, we have produced a regular multi-stage dc-dc resonant converter enhanced with topology of ideal boost converter. In this mechanism the traditionally used single switches were replaced instead of that number of clamped capacitor sub-modules are implemented. In which the converter is implemented with some resonance betweenthe arm inductor and sub-module clamped capacitors in a resonant mode. To provide a constant number the switching arrangement ofa phase-shifting operation is provided and supported by N of sub-capacitor modules at very high voltage. On this operation mode the count of sub-capacitor modules and the inductor charging ratio play a vital role which supports the step-up ratio. This converter has the capacity of bidirectional power flow and even without transformer it exhibits scalability. A wind turbine interface as an application example is shown with the conversion ratio 10:1 which is shown on simulation results. The proposed concept is experimentally verified with a laboratory-scaleprototype.
